(*) Azul provides two types of distribution packages for each Java version:
-
Subscriber Availability (SA) distributions are tested, certified, and commercially supported Azul Zulu Builds of OpenJDK. Azul ensures that the software that uses the Accessible APIs of the product doesn’t have to include specific licenses and that such a use doesn’t contaminate the code or intellectual property of such software with any license requirements. SA builds may support configurations and features that are unavailable to free users.
-
Community Availability (CA) distributions are Azul Zulu Builds of OpenJDK that are free to download and use.
|
Note
|
Both SA and CA distributions may contain Early Access builds noted with -ea- in their filename. Early Access builds may not be TCK certified.
|
(**) Update type:
-
CSPU (Critical Security Patch Update): Contains fixes to critical issues and security vulnerabilities, delivered on a monthly basis between regular quarterly update releases.
-
CSPU for CPU: Critical security patches applied to the latest quarterly CPU release.
-
CSPU for PSU: Critical security patches applied to the latest quarterly PSU release.
-
-
Out-of-Cycle for CPU: An update release published outside the regular quarterly schedule, based on a quarterly CPU release. It contains the content of that CPU, any CSPU-for-CPU fixes released since that CPU for the same package types, any earlier out-of-cycle update content, and the fix described in the "What’s New" section of this document.
-
CPU (Critical Patch Updates) contain fixes to security vulnerabilities and critical bug fixes. Azul Zulu CPU releases are generally based on prior-cycle PSU releases, with only security fixes applied. They provide a low-risk vehicle for the potentially urgent deployment of security fixes when issues of sufficient severity arise. CPU releases are available in SA distributions.
-
PSU (Patch Set Updates) incorporates all fixes in the corresponding CPU, as well as additional non-security bug fixes. Azul Zulu PSU releases incorporate both security fixes and other changes that align the release contents with the associated OpenJDK project quarterly release. PSU releases are available in SA and CA distributions.
What’s New
This update release removes certain CA certificates from the cacerts truststore of all Azul Zulu Builds listed in this document. It fixes a security issue related to the eMudhra Intermediate CA Compromise addressed in the Out-of-Cycle, October 21, 2026 Update.
